The problem this solves.

  1. 01
    The problem

    The village has arsenic in its water and no steady power supply.

    How it is fixed

    Water passes through a resin (small plastic beads) made to catch arsenic only. It removes both kinds of arsenic found in groundwater. Sensors send water quality readings to a phone or computer.

How it works

Step by step.

  1. 1

    Feed

    Groundwater flows into the resin column.

  2. 2

    Capture

    Small resin beads made to catch only arsenic hold it back.

  3. 3

    Monitor

    Sensors send flow and quality readings online.

  4. 4

    Supply

    Safe water goes to the village tap stand.

Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 9 of 9, which means: already in use. 1,000 litres an hour without electricity.

Can we try it on our own water first?

Yes. We test a sample in our NABL-accredited lab and, where it helps, run a small trial on your site before you invest in a full plant.

Do you supply and install it?

Yes. We design, supply, install and start up the system, train your staff, and our lab checks the treated water.
